bash脚本编程 - 来管理服务器导航 [英] Bash Scripting - to manage server navigation

问题描述

我写了一些的bash脚本围绕应用中管理时，使生活更轻松。

I am writing some bash scripts to make life easier when managing around an application.

脚本真的只是目录切换到我这节省了大量的时间最常见的位置。

The scripts really just change directories to my most common locations which saves a huge amount of time.

目前我有我的剧本在我的用户.bash_profile中，这很好地工作。

Currently I have my script in my users .bash_profile and this works nicely.

即

#SHORTENED COMMANDS
alias flushBash='source ~/.bash_profile'
alias editBash='sudo nano /home/gtec/.bash_profile'

#DIRECTORIES
alias gost='cd /var/www/location/of/directory'

从命令行我只需要输入：GOST和我带到我所选择的目录中。现在，上面是好的，如果我使用服务器然而，最终我将需要系统管理者等，所以我想我会写一个脚本来帮助第三方沿着唯一的一个。

From command line I just type: gost and I am taken to the directory of my choice. Now the above is fine if I am the only one using the server however, eventually I will need sys admins etc. so I figured I would write a script to help third parties along.

所以我增加了一个脚本来我的bash：

So I added a script to my bash:

#SCRIPTS
alias go='. /home/me/scripts/go.sh'

和的想法是，用户类型：走出去进入命令行，然后返回一个选项列表

And the idea is that the user types: "go" into the command line, and it then returns a list of options.

这是我迄今为止：

#!/bin/bash
clear
echo "Where do you want to go? home, anc-p, anc-s, auto-p, auto-s"
read -p "Enter a location :" location
if [$location = home]
then
  cd /home/gtec 
else
echo "Noting to do"
fi

当我运行在它上面的输出：

When I run the above it outputs:

Where do you want to go? home, anc-p, anc-s, auto-p, auto-s
Enter a location :home
[home: command not found
Noting to do

当我输入家返回主页：命令未找到...

and when I type in "home" it returns: home:command not found...

我我是做错了？

推荐答案

根据伊坦赖斯纳评论更新的答案，原来不准确的1 $ P $下面pserved。

主要的问题是语法：你需要的，如果周围的方括号的空间。此外，你应该总是给你的变量的情况下，它们包含空格字符。解决方法：

The main problem is syntactical: you need spaces around the square brackets of the if. Furthermore, you should always quote your variables in case they contain whitespace characters. Solution:

#!/bin/bash
clear
echo "Where do you want to go? home, anc-p, anc-s, auto-p, auto-s"
read -p "Enter a location : " location
if [ "$location" = "home" ]
then
  cd /home/gtec 
else
  echo "Nothing to do"
fi

原件，以供参考不准确的回答是：

Original, inaccurate answer for reference:

您在您若2错误：首先，你跟 = 分配，而不是与测试== ，其次你错过的空白。下面是它应该是什么样子：

You have 2 mistakes in your if: firstly, you assign with = instead of testing with ==, secondly you're missing whitespace. Here's what it should look like:

#!/bin/bash
clear
echo "Where do you want to go? home, anc-p, anc-s, auto-p, auto-s"
read -p "Enter a location :" location
if [ $location == home ]
then
  cd /home/gtec 
else
echo "Nothing to do"
fi

的误差（1）表明谎称 == 是唯一的选择;（2）省略了双引号。

The inaccuracy lied in (1) suggesting that == is the only option and (2) omitting the double quotes.
